6 Claims.

This application is a division of my copending application filed May 28, 1932, Serial No. 614,091 a part of which has matured March 31, 1936 as Patent No. 2,036,043.

My invention relates to ice tray release mechanism and release mechanism for grids of ice trays. The nature of the invention will be apparent from the following description taken in conjunction with the accompanying drawing forming a part of this specification, and of w 10 Fig. 1 is a plan view of a device embodying the invention;

Fig. 2 is a front view;

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2; and

Fig. 4 is a sectional View taken on the line 4-4 of Fig. 3.

The ice tray to which the invention is applied includes a tray body 10. The tray body l rests on a shelf l2 of an evaporator. The forward part of the tray body is formed with a horizontal part l3, a downwardly extending flange or depending part l4, and a rearwardly extending part IS. The upper horizontal part I3 is formed with an aperture to receive a neck I 6 which is attached to a grid contained in the tray body in any suitable manner and which projects downwardly through part l3. The forward'part I4 is formed with a circular aperture of large diameter to receive a circular head ll. Head I! is formed with a cam surface at I8 as shown in Fig. 4. Neck l6 bears against the cam surface l8 so that when the member I! is rotated clockwise as shown in Fig. 2 the neck I6 is pushed upwardly for release of the grid. A downwardly pfijecting member I9 is pivoted at 20 on the member I1 and extends through a slot 2| in the lower part l of the tray body extension. Member I9 is adapted to contact the shelf [2 and, on turning the member ll, the member l9 projects downwardly below the tray body to cause release thereof from the shelf.

A bump 22 is formed in the tray body which constitutes a bearing member for a projection 23 on member Il. At the forward part of member I1 is a handle member 25 which projects through a slot 26 formed in the upper part of a handle portion 21 of a front cover plate 28. The handle part 21 is of the drawer type in which the fingers are projected upwardly. The slot forms a guide for the handle member 25 and the member I! is prevented from having longitudinal movement due to the cooperation of the handle or lever part 25 with the slot 26.

If the handle part 25 is turned clockwise as shown in Fig. 2, it will turn the member I! and cause the member l9 to project downwardly to release the tray and the part IE will ride on the cam surface I 8 so as to release the grid.

What I claim is:

1. Ice making apparatus including a tray body, a front plate attached to said body having a horizontally extending slot therein, and a leverage member extending through said slot.

2. Ice making apparatus including a tray body,

a front plate attached to said tray body having a handle portion and formed with a slot at the top of the handle portion, and a lever extending through said slot.

3. Ice making'apparatus including a tray body,

a front plate attached to said tray body having a horizontally extending slot therein, and leverage mechanism mounted on said tray body and including a handle extending through said slot and a part adapted to be extended from a retracted position to such position that a portion of it extends below the tray body.

' 4. vIce making apparatus including a tray body,

a front plate attached to saldbody having a slot 30 therein, and lever mechanism including a handle part extending through said slot, said slot constituting positioning means for said lever mechanism.

5. Ice making apparatus including a tray body having a forward extension, leverage mechanism journalled in said forward extension and on said tray body, and guide means for said leverage mechanism including a handle part.

6. An ice tray for a refrigerator including a tray body having a forward extension, a rotatable member journalled in said extension and on the tray body, a depending member pivoted on said rotatable member, and a front plate attached to said tray body, said rotatable member being held
